Embodiment 1

[0054] A kind of high-quality winter jujube protected cultivation method, comprises the following steps:

[0055] (1) Selection of venue

[0056] It is advisable to choose plots with clean air and water quality, flat and open terrain, sufficient sunlight, fertile and unpolluted soil, and good drainage and irrigation conditions. Slopes, etc.;

[0057] (2) Greenhouse construction

[0058] The greenhouses are 8-span north-south greenhouses. The 8-span greenhouses have a large space, are convenient for automation and mechanization, and have a land utilization rate of up to 90%. It can be adjusted according to the length of the field. The side height of the second shed in the shed is 2.5m, the ridge height is 4.5m, the main column and the main beam are set every 4m, and the auxiliary bracket is set every 1m. Films, insect nets, windproof ropes, automatic blower fans, water and fertilizer integration and other mechanized equipment are installed in the shed;

[0059] (3) Field pr...

Embodiment 2

[0091] The difference between embodiment two and embodiment one is:

[0092] The step (3) field arrangement: 1.25 tons of commercial organic fertilizers with a total content of 5% of N, P, and K in the fields ready for planting ditch, and 35cm of rotary tillage;

[0093] Said step (6) fertilizer management: apply fruit fertilizer at the beginning of July, when the growth condition of the tree body is good, 13kg / mu of sulfur-based ternary compound fertilizer, if the tree body appears the symptom of fertilizer deficiency, can apply 2 times of water-soluble fruit fertilizer Fertilizer, the first application in early July, the second application 20 days later, each application of sulfur-based ternary water-soluble fertilizer 10kg / mu, after the fruit harvest at the end of November and early December, apply winter fertilizer once to supplement plant nutrition, sulfur-based Ternary compound fertilizer 25kg / mu;

[0094] Described step (9) adopts small-scale mechanical rotary tillage ...

Embodiment 3

[0097] The difference between embodiment three and embodiment one is:

[0098] The step (3) field arrangement: 1.5 tons of commercial organic fertilizers with a total content of 5% of N, P, and K are sprinkled on the fields ready for planting ditch, and 40cm of rotary tillage is used;

[0099] Said step (6) fertilizer management: apply fruit fertilizer at the beginning of July, when the growth condition of the tree body is good, the sulfur-based ternary compound fertilizer is 15kg / acre, if the tree body appears the symptom of fertilizer deficiency, can apply 2 times of water-soluble fruit fertilizer Fertilizer, the first application in early July, the second application 20 days later, each application of sulfur-based ternary water-soluble fertilizer 12kg / mu, after the fruit harvest at the end of November and the beginning of December, the winter fertilizer was applied once to supplement plant nutrition. The same fertilizer and fertilization method as spring fertilizer, sulfur-...

Abstract

The invention discloses a facility cultivation method for high-quality winter jujube, which comprises the following steps: selection of a field, construction of a greenhouse, preparation of field plots, value determination of saplings, temperature management, management of fertilizer and water, tree type pruning, rotation of fruiting backbone branches, and bee-assisted pollination It belongs to the field of crop planting related to fruit thinning, intertillage weeding, and pest control. The invention creates a special and controllable community environment for fruit trees, avoids natural rain, flexibly adjusts irrigation periods and irrigation volumes, and ensures that trees and fruits grow and develop every day. The best irrigation effect can be obtained in the first stage, which reduces the fruit cracking rate of winter jujube, improves fruit quality and commodity rate, facility cultivation can also effectively control the occurrence and spread of various diseases and insect pests, apply less or no pesticides, and contribute to pollution-free production Green fruit has opened up an effective way to rationally apply fertilizers and use biopesticides to promote the growth and development of fruit trees, produce high-quality, high-yield high-quality winter jujube fruits, and protect the agricultural ecological environment.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a method for facility cultivation of high-quality winter jujube. Background technique [0002] Dongzao belongs to Rhamnaceae, Jujube genus. It is an excellent late-maturing and fresh variety of thornless jujube. It usually matures naturally from October to November in the Gregorian calendar. Because the weather in the north is cold earlier, it is named "Dongzao". It is distributed in Shanxi, Hebei, Shandong and other places. The average single fruit weight is 17.5g, and the maximum single fruit weight can reach 25g. It is shaped like an apple and is called "little apple". The peel is reddish red and bright, the skin is thin, the meat is crisp, the meat is tender, juicy and slag-free, sweet and fragrant, and the edible rate reaches 95%. Winter jujube is not only delicious, but also very nutritious. Contains 19 kinds of amino acids needed by the human body, such as asparti...
